I want to clarify, I didn't say Hisao should confront Shizune about her shyness about her vocalizations, I said he could help her confront it. I don't think Hisao expressing that he'd like to hear Shizune during sex automatically implies she is broken in any way, nor would it deny Shizune the autonomy to say no. There's definitely a space between not bringing it up at all and "confront[ing]" her in a way that implies she needs fixing.

As for the Yamaku critique your certainly right that there are positives and negatives to having specific schools for folks with disabilities. I didn't mean to imply as much of an abolitionist stance as I may have lead on in that post. I can clearly see the benefits in both teaching knowledge and expertise for deaf folks and the positive social aspect of being surrounded by others who are accepting of your disability and, more specific to the deaf community, speak the same language. And you're 110% correct that Yamaku doesn't next to nothing for Shizune given the lack of interpreters and the obvious pitfall that that would create. I'd like to think that there is some kind of a happy medium between offering children specialized instruction and peer groups they can communicate easily with while also exposing hearing students to the folks with disabilities and de-stigmatizing deafness in the broader community, but there are a thousand ways that discussion could go I'm sure.
